Dimerization quality control ensures neuronal development and survival

6 hours ago from Science NOW

Aberrant complex formation by recurrent interaction modules, such as BTB domains, leucine zippers, or coiled coils, can disrupt signal transduction, yet whether cells detect and eliminate complexes of irregular composition...

Discovery of widespread type I and type V CRISPR-Cas inhibitors

6 hours ago from Science NOW

Bacterial CRISPR-Cas systems protect their host from bacteriophages and other mobile genetic elements. Mobile elements, in turn, encode various anti-CRISPR (Acr) proteins to inhibit the immune function of CRISPR-Cas. To...

Systematic discovery of natural CRISPR-Cas12a inhibitors

6 hours ago from Science NOW

Cas12a (Cpf1) is a CRISPR-associated nuclease with broad utility for synthetic genome engineering, agricultural genomics, and biomedical applications. Although bacteria harboring CRISPR-Cas9 or CRISPR-Cas3 adaptive immune systems sometimes acquire mobile...

Genome hypermobility by lateral transduction

6 hours ago from Science NOW

Genetic transduction is a major evolutionary force that underlies bacterial adaptation. Here we report that the temperate bacteriophages of Staphylococcus aureus engage in a distinct form of transduction we term...

Homology, neocortex, and the evolution of developmental mechanisms

6 hours ago from Science NOW

The six-layered neocortex of the mammalian pallium has no clear homolog in birds or non-avian reptiles. Recent research indicates that although these extant amniotes possess a variety of divergent and...

Microglia and early brain development: An intimate journey

6 hours ago from Science NOW

Cross-talk between the nervous and immune systems has been well described in the context of adult physiology and disease. Recent advances in our understanding of immune cell ontogeny have revealed...

Glia as architects of central nervous system formation and function

6 hours ago from Science NOW

Glia constitute roughly half of the cells of the central nervous system (CNS) but were long-considered to be static bystanders to its formation and function. Here we provide an overview...

Neuronal specification in space and time

6 hours ago from Science NOW

To understand how neurons assemble to form functional circuits, it is necessary to obtain a detailed knowledge of their diversity and to define the developmental specification programs that give rise...
